Airaid 200-585-1 Throttle Body Spacer | 2007-2013 GM Silverado/Sierra 4.3L

The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it’s unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer.

The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power. 

The AIRAID 200-585-1 fits some Chevrolet Colorado, Chevrolet Silverado 1500, Chevrolet Silverado 1500 Classic, GMC Canyon, GMC Sierra 1500, GMC Sierra 1500 Classic, Isuzu i-280, and Isuzu i-290 models. See vehicle applications for details.
